Which acupuncture point is located in the depression on the lower border of the clavicle, 2 cun lateral to the midline?

• A. KD 26
• B. KD 27
• C. PC 1
• D. REN-13

Answer: (B)

The main idea here is using precise chest landmarks and the cun measurement to locate a point. The description “in the depression on the lower border of the clavicle, 2 cun lateral to the midline” matches the Kidney channel point that sits right under the clavicle in that hollow, at about the first intercostal space. This point is KD-27 (Shen Guan). It lies two cun away from the body's midline and just below the clavicle, so the given location points directly to this point.

The other options would be found in different spots on the chest or midline areas, so they don’t fit the described landmark. KD-27 is the one that exactly matches that clavicular depression two cun from the midline.
